Abstract (en)

[origin: EP0517979A1] A process for producing an aromatic acylation product from an aromatic compound, an olefin and carbon monoxide, which comprises the steps of: (a) reacting an olefin with carbon monoxide in the presence of hydrogen fluoride and boron trifluoride at a pressure of not more than 100 kg/cm<2>G to prepare an acyl fluoride synthesis solution, (b) allowing the acyl fluoride synthesis solution to absorb boron trifluoride to form a complex of acyl fluoride and boron trifluoride, (c) subjecting an aromatic compound to an acylation reaction with a reaction mixture containing the complex of acyl fluoride and boron trifluoride, obtained in the step (b), to form a complex of boron trifluoride, hydrogen fluoride and an aromatic acylation compound, and (d) separating the aromatic acylation compound from the complex formed in the step (c) by heating a reaction mixture obtained in the step (c). e
